#1 my alarm clock, any alarm clock waking me up at 5:00 am for that matter.

#2 the printer/scanner/copier in my office. loud and used constantly.
Guess what? It is out of service as of an hour ago. muwahahahaha but I didn't have anything to do with it, just glad. I hope the copier dude doesn't show up for days.

1) Incessantly barking dogs- whose owners need to be publicly whipped, in my world.
2) People with terrible manners smacking while they eat....eeewwww
3) Any repeated and unusual noises coming from the engine compartment of any vehicle I'm driving or riding in.

3. People who yawn really loud. It drives me nuts, if I can make a yawn very quiet SO CAN YOU!

Further to that - it makes me cringe when people do things like sneeze really loudly and dont cover their mouths or blow their noses really loud...i guess those two things bother me most in restaruants, elevators and doctors offices...and maybe that is more of an OCD thing on my part though...LOL

We used to also have this older woman who worked in my office and she used to eat a bowl of soup for lunch everyday and then belch really loudly after she finished...she was only in the US for a short time and told people that it was not considered offensive in her country...contrarily, it was considered a sign of a healty appetite...
